I got stuck with a dsl modem awhile back and it was free with the dsl service. Sbc stuck me with a dynamic ip address so i cant put up a ftp like i would otherwise. I have a wireless linksys router and it has a port forwarding option. Im attempting to set up a ftp using no-ip.com but its not working so well. As far as i see ive gotten everything besides the port forwarding part down. The software works and it shifts IPs every 20 secs. But my problem is i cant use it. Im positive its the portforwarding that screwing up on the router but i can't seem to figure it out.
If i didn't explain it well enough heres the guy at no ip explaining the same senario.

Hi Bob and :welcome: One of our techies will be here to answer your problem shortly.

Hi Bob, Have you tried accessing it from another PC thats not on your LAN as it says in that article :
When testing your webserver, the external IP address may not work from inside your local network. Consider having a friend on a different network connection bringing up your website.
-
you might have something there. the problem is most of my friends are at work right now. mmmm.
try this
ftp://bob:bob@bobscrachy.redirctme.net
tell me if you get anything
-
Sorry Bob "Server address not resolved", still it was worth a try ???
-
Have you got open permissions to allow anyone to access your FTP site Bob as I get that message on username/password protected sites that I have visited ???
-
well, lets give it another try, i screwed with the permissions and gave you full access you were only on guest before. Im not sure if this will matter much, but like you said its worth a try.
Don't fret if we don't get it to working today, im sure to keep at it until i get it working correctly and then ill post the solution to help anyone that might have the same problem
-
Sorry Bob still same message ???
I hope we can get it sorted as I want to set a sever up using No IP too, sometime in the near furure, as mines a dynamic IP too although it is a "sticky" one and hasnt changed since I got ADSL about 15 months ago :doggie:
-
I just clicked on the link and outlook express launched :)
Was it supposed to do that ???
-
No GK you need to copy and paste the full url into the browser to try it.
I tried to edit it to correct it by adding the tags at either end but that didnt work the same way as it does for HTTP sites ???
-
Hi Bobscrachy :welcome:
I just pinged your domain and that seems to be responding. So it means that the dynamic DNS bit is working OK.
So the problem must lie in the port redirection on the router.
If I understand it correctly (I've used port redirection a few times) you need to set the router up so that all traffic to port 21 (FTP) is sent to the local address of your ftp server. So if your FTP server is on the local address 192.168.0.2 you would set a port redirection of port 21 to address 192.168.0.2. I'm sure you know all of that ;)
The only reason I can think of to make it go wrong is if the router or the FTP server have a firewall which blocks port 21. If the FTP server PC is running Windows XP, make sure that the built-in Windows firewall isn't blocking that port :)
Hope this helps.
-
well heres the deal. Im using warftp. and ive set the server up before and its on a win98 machine. I knew the domain worked. The problem was i tryed the port forwarding on my router. I thought i the port forwarding right but i have no idea if i did or not because i haven't had any experiance on forwarding. I see a load of options and i have no idea which option does what. I guess im going to half to dive deep into the user manual to see wth im doing wrong.
-
Not sure if this will help Bob but according to this :
http://www.homenethelp.com/web/explain/port-forwarding-dmz.asp
It suggests that FTP servers run on port 23 and HTTP on 80, not both on 80 ???
-
Found this as well Bob, I read somewhere that you use the same port number in both parts of the port forwarding page :doggie:
http://www.e-league.com/linksys.htm
-
yea i found this site, its for gaming with a dynamic ip. the problem with this is it screwed up my net browsing so i couldn't go to my forum. I turned off the settings i set from this page and things returned to normal. This page seems to be for hosting games though. Im not sure if theres a big difference but it still didn't alow my ftp to work.
-
you know i may be shooting in the dark, but i wonder if trying to do this on a wireless router is the problem?.....
-
Sandra. Not sure where you got the info about port 23 for ftp. 23 is used for Telnet.
FTP is definately and port 21. I have a feeling that port 20 is also used by the server, but I'm not sure what for.
If that Linksys web site shows the same screens as Bob's router the forwarding should be set up as:-
Ext Port
20 to 20
Protocol TCP
checked
Protocol UDP
unchecked
IP address
The internal IP address of the FTP machine
Enable
Checked
Not sure where all that empty space came from :o That's what happens when you try and be fancy and use tables ::)
-
from what i understand is that the dmz host is suppose to put the ip number you select as the receiver for all the ports while at the same time giving up security by being outside the routers firewall. I tried doing this just to see if as a last option i could get the server to work and to check weither or not it was a port problem.... Guess the answer. It still doesn't work. Which leads me to think either theres some unknown option im over looking that would prevent the router from doing what i ask it to do or theres a problem with the software in either the ftp or the no-ip progs. But then again theres always the thought that it might be something with the wireless connection. mysteries????? im going to put a ftp on the comp in my other room beside the router to test if its the wireless or not. then im going to switch ftp progs if that lends no answers.
-
well it is definatly something with the router, i connected a pc directly up too the dsl modem and the ftp works fine now. I must screw more with the router to see what im doing wrong or if its just a glitch.
just thought yall might like this pic lmao, i actually own one

I couldn't view your pic Bob. :'(
-
i put the router back up so i could have internet in the other room. sorry man. if u really want to see it i could put again but i want to get the router working right so i don't half to disconnect it everytime i want to move or host something.
-
It's OK Bob, I will just worship Sandra's instead. :lol:
-
problem solved yet another pops up.
The port forwarding and dmz host were working i just didn't know it. the no-ip soft had a box that needed to be checked to start the refreshing of the ip address.
Summary- my dumba** missed something simple.
Secondary chain-reaction problem. In my attempt to access the ftp using port forwarding i noticed it was accessing the ftp but couldn't veiw anything. So i changed it to dmz host which puts the host computer outside the router's firewall.
Conclusion the dmz host worked by letting all the ports be seen.
a friend suggested i check the box for passive ftp in the settings box in the ie settings. or use a ftp prog like cuteftp. But when i went looking for the option in my v5.0 ie it didnt show it. So i upraded, still no passive option.
Is this a flaw with 98 or a flaw with the ie upgrade. or just something really really odd with my version of 98

I don't know CuteFTP (I use SmartFTP (http://www.smartftp.com)), but usually Passive is an option in the connection settings for the FTP site. There is often a "master setting" in the preferences for the program too. SmartFTP has an toolbar button to press before connection.
As for placing your PC in the DMZ, be very careful as this will be outside of the routers firewall. You could be vulnerable to attack unless you have blocked all ports other than the FTP ones.
You might find this article (http://www.unixcities.com/ftp-and-firewall/) and this article (http://slacksite.com/other/ftp.html) interesting :)

Ive always wondered why they would come up with rules like these instead of just haveing it simplifed for the common user, guess now i know.
i know the dangers of using dmz host thats why im looking for a passive mode option in my ie. so i can use port forwarding instead of dmz host.

Hi Bob, I dont know if this will help you or not.
I use Bluzone FTP,(now changed its name to Seagull), its free and has an enable Passive FTP option in the miscellaneous section of the properties when you add a new or edited FTP setting :)

the problem isn't with the ftp anymore. the problem is a Q&A about the windows internet explorer. If you check your settings look for passive mode in your ie. for some reason im fully upgraded and yet the option for passive mode isn't there. i really want passive mode for an option in the ie if i can get it just because im lazy and i don't want to switch right this moment. I mean what can i do to get passive mode on the ie if its fully upgraded? Is there a way to uninstall and fully reinstall the built in explorer of windows? Lmao, this american has caused yall so much trouble. Just so i don't sound ungrateful thank you all for your thoughts and ideas on this subject.
-
Hi Bob, do you mean that this option isnt showing on yours under Tools, Internet Options and Advanced ???
-
nope, im thinking its because my comp is a 98 but that isn't there ive checked many-a-time already. any suggestions on how to get it there lmao.
